What is Tailwind CSS?

Tailwind CSS is a utility-first CSS framework for building custom website interfaces quickly. Unlike traditional frameworks with pre-designed components, it offers low-level utility classes. These act like Lego blocks for website design. Instead of writing tons of CSS code, you simply use these pre-built classes to style your website. This makes creating unique designs faster and easier.

Tailwind CSS integrates seamlessly with React, a popular tool for building interactive website interfaces. This lets you style your website directly within your JavaScript code. Tailwind offers more efficiency and flexibility compared to regular CSS. Imagine having a pre-made Lego set instead of building each block from scratch! Plus, making design changes is easier – just swap out one class for another.

Installation and Setup

Installing Tailwind CSS and Dependencies

Let's get Tailwind CSS up and running in your React project! We'll need a few additional tools to make it work smoothly.

Firstly, open your terminal in the project directory and run the following command:

npm install tailwindcss postcss autoprefixer

This installs Tailwind CSS itself, along with PostCSS and Autoprefixer.

  • PostCSS is a tool for transforming styles with JavaScript plugins. These plugins can do a lot of things like linting your CSS, supporting variables and mixins, transpiling future CSS syntax, inlining images, and more.
  • Autoprefixer is a PostCSS plugin. It uses data based on current browser popularity and property support to automatically add any necessary vendor prefixes to your CSS. This ensures that your CSS works as expected in different browsers, even those that require specific prefixes for certain CSS features.

Configuration Files

  • Create tailwind.config.js in your project root. This file tells Tailwind where to find the parts of your React application that contain styles (usually inside the src folder).
module.exports = {
    content: ['./src/**/*.{js,jsx,ts,tsx}'], theme: {
        extend: {},
    }, plugins: [],
  • Create postcss.config.js in your project root. This file tells PostCSS which plugins to use.
module.exports = {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},

Importing Tailwind CSS

Finally, open your src/index.css file and add the following lines at the top:

@tailwind base;
@tailwind components;
@tailwind utilities;

That's it! Now you have Tailwind CSS set up and ready to use in your React components. We'll explore how to style your React elements with Tailwind CSS classes in the next section.

      <Hero />
      <Analytics />
      <Newsletter />
      <Cards />
      <Footer />

export default App;

Build A Navigation Bar

In the Navbar.jsx component, check the code in src/components/Navbar.jsx:

import React, { useState } from 'react';
import { AiOutlineClose, AiOutlineMenu } from 'react-icons/ai';

const Navbar = () => {
  const [nav, setNav] = useState(false);

  const handleNav = () => {

  return (
    <div className='flex justify-between items-center h-24 max-w-[1240px] mx-auto px-4 text-white'>
      <h1 className='w-full text-3xl font-bold text-[#00df9a]'>REACT.</h1>
      <ul className='hidden md:flex'>
        <li className='p-4'>Home</li>
        <li className='p-4'>Company</li>
        <li className='p-4'>Resources</li>
        <li className='p-4'>About</li>
        <li className='p-4'>Contact</li>
      <div onClick={handleNav} className='block md:hidden'>
          {nav ? <AiOutlineClose size={20}/> : <AiOutlineMenu size={20} />}
      <ul className={nav ? 'fixed left-0 top-0 w-[60%] h-full border-r border-r-gray-900 bg-[#000300] ease-in-out duration-500' : 'ease-in-out duration-500 fixed left-[-100%]'}>
        <h1 className='w-full text-3xl font-bold text-[#00df9a] m-4'>REACT.</h1>
          <li className='p-4 border-b border-gray-600'>Home</li>
          <li className='p-4 border-b border-gray-600'>Company</li>
          <li className='p-4 border-b border-gray-600'>Resources</li>
          <li className='p-4 border-b border-gray-600'>About</li>
          <li className='p-4'>Contact</li>

export default Navbar;

Here’s how Tailwind is used:

  • Responsive Design: Tailwind is used to control how the navigation menu appears on different screen sizes. For example, the md:hidden class hides the navigation menu on medium and larger screens, while the md:flex class displays it as a flex container. The navigation bar displays as a horizontal menu on medium and large screens, and as a collapsible vertical menu on smaller screens.
  • Styling: Tailwind provides a wide range of utility classes for styling. Our Navbar uses classes like h-24 (height), max-w-[1240px] (maximum width), and mx-auto (margin left and right auto) to define the container's size and position. We also use text-white for clear text on a dark background.
  • State Management: The useState hook from React is used to manage the state of the navigation menu on small screens. When the menu icon is clicked, the handleNav function toggles the nav state between true and false. This state is used to control the display of the navigation menu on small screens.
  • Conditional Rendering: Tailwind classes are dynamically applied based on the nav state to show or hide the navigation menu on small screens. If nav is true, the menu is displayed as a fixed, full-height panel on the left side of the screen. If nav is false, the menu is hidden off the left edge of the screen.
  • Icons: The AiOutlineClose and AiOutlineMenu icons from the react-icons/ai library are used for the close and menu buttons, respectively. These buttons are displayed or hidden based on the nav state.

Build A Hero Section

The hero section is a crucial part of your website, grabbing user attention and conveying your message. In Hero.jsx ,this code creates a hero section with a typing animation and a button:

import React from 'react';
import Typed from 'react-typed';

const Hero = () => {
  return (
    <div className='text-white'>
      <div className='max-w-[800px] mt-[-96px] w-full h-screen mx-auto text-center flex flex-col justify-center'>
        <p className='text-[#00df9a] font-bold p-2'>
        <h1 className='md:text-7xl sm:text-6xl text-4xl font-bold md:py-6'>
          Grow with data.
        <div className='flex justify-center items-center'>
          <p className='md:text-5xl sm:text-4xl text-xl font-bold py-4'>
            Fast, flexible financing for
          className='md:text-5xl sm:text-4xl text-xl font-bold md:pl-4 pl-2'
            strings={['BTB', 'BTC', 'SASS']}
        <p className='md:text-2xl text-xl font-bold text-gray-500'>Monitor your data analytics to increase revenue for BTB, BTC, & SASS platforms.</p>
        <button className='bg-[#00df9a] w-[200px] rounded-md font-medium my-6 mx-auto py-3 text-black'>Get Started</button>

export default Hero;

Here's how we apply Tailwind CSS:

  • Layout and Responsiveness: The max-w-[800px] class ensures the hero section adapts well to different screen sizes. The w-full class utilizes the full available width within its container, and h-screen sets the height to match the user's screen. mx-auto helps center the content horizontally for a balanced look.
  • Text Styling: The text-white class makes the text stand out against the background. Headings utilize responsive classes (md:text-7xl, sm:text-6xl, text-4xl) to adjust their size based on the device viewport. The font-bold class adds boldness to the headings for emphasis.
  • Flexbox for Alignment: The flex class creates a flex container, while flex-col stacks elements vertically. justify-center centers the content vertically within the flex container.
  • Typing Animation: The Typed component is a wrapper around the typed.js library which creates a typing animation for the strings provided in the strings prop.
  • Call to Action Button: bg-[#00df9a] class sets a custom background color for the button, and text-black ensures the button text is clearly visible. Other classes like w-[200px] (width), rounded-md (rounded corners), my-6 (margin), and py-3 (padding) define the button's appearance and spacing.

When rendering Hero component, it looks like this:

Build An Analytics Section

Analytics.jsx represents a section of a webpage. It includes a div container with two main sections arranged in a grid layout on medium and larger screens:

import React from 'react';
import Laptop from '../assets/laptop.jpg';

const Analytics = () => {
  return (
    <div className='w-full bg-white py-16 px-4'>
      <div className='max-w-[1240px] mx-auto grid md:grid-cols-2'>
        <img className='w-[500px] mx-auto my-4' src={Laptop} alt='/' />
        <div className='flex flex-col justify-center'>
          <p className='text-[#00df9a] font-bold '>DATA ANALYTICS DASHBOARD</p>
          <h1 className='md:text-4xl sm:text-3xl text-2xl font-bold py-2'>Manage Data Analytics Centrally</h1>
            Lorem ipsum dolor sit amet consectetur adipisicing elit. Voluptatum
            molestiae delectus culpa hic assumenda, voluptate reprehenderit
            dolore autem cum ullam sed odit perspiciatis. Doloribus quos velit,
            eveniet ex deserunt fuga?
          <button className='bg-black text-[#00df9a] w-[200px] rounded-md font-medium my-6 mx-auto md:mx-0 py-3'>Get Started</button>

export default Analytics;

Analytic component UI rendering will look like this:


Here’s a simple explanation of what the Tailwind CSS classes do in this code:

  • Layout and Responsiveness: The w-full, bg-white, py-16, px-4 classes set the overall container with full width, white background, and padding. max-w-[1240px] ensures a maximum width for larger screens. On medium and larger screens (md:grid-cols-2), the content is arranged in a two-column grid layout with grid.
  • Image and Text Arrangement: The image is styled with w-[500px] for a fixed width. The text content utilizes flex flex-col justify-center for a vertical column with centered elements.
  • Button Styling: The button receives a black background with bg-black, green text with text-[#00df9a], and common styling classes like w-[200px] (width), rounded-md (rounded corners), and padding (py-3). Responsive margins (mx-auto md:mx-0) center the button on smaller screens but remove margins on medium and larger ones.

Build A Newsletter Section

Newsletter.jsx defines the structure and appearance of the newsletter section.

import React from 'react';

const Newsletter = () => {
  return (
    <div className='w-full py-16 text-white px-4'>
      <div className='max-w-[1240px] mx-auto grid lg:grid-cols-3'>
        <div className='lg:col-span-2 my-4'>
          <h1 className='md:text-4xl sm:text-3xl text-2xl font-bold py-2'>
            Want tips & tricks to optimize your flow?
          <p>Sign up to our newsletter and stay up to date.</p>
        <div className='my-4'>
          <div className='flex flex-col sm:flex-row items-center justify-between w-full'>
              className='p-3 flex w-full rounded-md text-black'
              placeholder='Enter Email'
            <button className='bg-[#00df9a] text-black rounded-md font-medium w-[200px] ml-4 my-6 px-6 py-3'>
              Notify Me
            We care bout the protection of your data. Read our{' '}
            <span className='text-[#00df9a]'>Privacy Policy.</span>

export default Newsletter;

Newsletter component UI will look like this:

Newsletter component UI

Here’s how Tailwind is used:

  • w-full py-16 text-white px-4 establishes a full-width container with white text and padding. Responsive layouts are achieved with max-w-[1240px] for a maximum width and grid lg:grid-cols-3 for a two-column layout that adapts to three columns on larger screens.
  • The form integrates seamlessly with flex flex-col sm:flex-row, switching between a vertical stack on smaller screens and a horizontal layout on larger ones.  
  • Common styling classes like rounded-md and text-black are applied to the input field and button. The privacy policy link is styled with text-[#00df9a] to match the green theme without being visually overwhelming.

Build A Grid of Three Cards

This is a React component named Cards that renders a grid of three cards. Each card represents a different user plan: Single User, Double User, and Triple User. Each card displays an image, a title, a price, and a list of features. There’s also a “Start Trial” button on each card.

import React from 'react';
import Single from '../assets/single.png'
import Double from '../assets/double.png'
import Triple from '../assets/triple.png'

const Cards = () => {
  return (
    <div className='w-full py-[10rem] px-4 bg-white'>
      <div className='max-w-[1240px] mx-auto grid md:grid-cols-3 gap-8'>
          <div className='w-full shadow-xl flex flex-col p-4 my-4 rounded-lg hover:scale-105 duration-300'>
              <img className='w-20 mx-auto mt-[-3rem] bg-white' src={Single} alt="/" />
              <h2 className='text-2xl font-bold text-center py-8'>Single User</h2>
              <p className='text-center text-4xl font-bold'>$149</p>
              <div className='text-center font-medium'>
                  <p className='py-2 border-b mx-8 mt-8'>500 GB Storage</p>
                  <p className='py-2 border-b mx-8'>1 Granted User</p>
                  <p className='py-2 border-b mx-8'>Send up to 2 GB</p>
              <button className='bg-[#00df9a] w-[200px] rounded-md font-medium my-6 mx-auto px-6 py-3'>Start Trial</button>
          <div className='w-full shadow-xl bg-gray-100 flex flex-col p-4 md:my-0 my-8 rounded-lg hover:scale-105 duration-300'>
              <img className='w-20 mx-auto mt-[-3rem] bg-transparent' src={Double} alt="/" />
              <h2 className='text-2xl font-bold text-center py-8'>Single User</h2>
              <p className='text-center text-4xl font-bold'>$149</p>
              <div className='text-center font-medium'>
                  <p className='py-2 border-b mx-8 mt-8'>500 GB Storage</p>
                  <p className='py-2 border-b mx-8'>1 Granted User</p>
                  <p className='py-2 border-b mx-8'>Send up to 2 GB</p>
              <button className='bg-black text-[#00df9a] w-[200px] rounded-md font-medium my-6 mx-auto px-6 py-3'>Start Trial</button>
          <div className='w-full shadow-xl flex flex-col p-4 my-4 rounded-lg hover:scale-105 duration-300'>
              <img className='w-20 mx-auto mt-[-3rem] bg-white' src={Triple} alt="/" />
              <h2 className='text-2xl font-bold text-center py-8'>Single User</h2>
              <p className='text-center text-4xl font-bold'>$149</p>
              <div className='text-center font-medium'>
                  <p className='py-2 border-b mx-8 mt-8'>500 GB Storage</p>
                  <p className='py-2 border-b mx-8'>1 Granted User</p>
                  <p className='py-2 border-b mx-8'>Send up to 2 GB</p>
              <button className='bg-[#00df9a] w-[200px] rounded-md font-medium my-6 mx-auto px-6 py-3'>Start Trial</button>

export default Cards;

UI rendering would be like this:


Let's analyze how Tailwind is used:

  • The outer container (w-full py-[10rem] px-4 bg-white) establishes a full-width section with white background and padding.
  • The inner content utilizes max-w-[1240px] for a maximum width and grid md:grid-cols-3 gap-8 to create a one-column layout on small screens, transitioning to three columns on medium and larger ones with spacing (gap-8).
  • Individual cards are styled with shadow-xl for depth, flex flex-col for vertical arrangement, and rounded-lg for gentle corners. The hover effect (hover:scale-105 duration-300) slightly enlarges the card on hover for better interactivity.
  • Image placement and styling are handled within each card's img tag. Card titles (text-2xl font-bold text-center py-8) and prices (text-center text-4xl font-bold) utilize clear styles. Features are listed with text-center font-medium, and borders are added with border-b mx-8 for separation.
  • Start trial buttons (bg-[#00df9a] w-[200px] rounded-md font-medium my-6 mx-auto px-6 py-3 for green ones and bg-black text-[#00df9a] for the black one) receive consistent styling with variations in background color and text color.

Build A Footer Section

Finally, the Footer component creates a responsive footer section with social media icons and navigation links. The footer is divided into four main sections: a logo and description, solutions, support, and company information.

import React from 'react';
import {
} from 'react-icons/fa';

const Footer = () => {
  return (
    <div className='max-w-[1240px] mx-auto py-16 px-4 grid lg:grid-cols-3 gap-8 text-gray-300'>
        <h1 className='w-full text-3xl font-bold text-[#00df9a]'>REACT.</h1>
        <p className='py-4'>Lorem, ipsum dolor sit amet consectetur adipisicing elit. Id odit ullam iste repellat consequatur libero reiciendis, blanditiis accusantium.</p>
        <div className='flex justify-between md:w-[75%] my-6'>
            <FaFacebookSquare size={30} />
            <FaInstagram size={30} />
            <FaTwitterSquare size={30} />
            <FaGithubSquare size={30} />
            <FaDribbbleSquare size={30} />
      <div className='lg:col-span-2 flex justify-between mt-6'>
        <h6 className='font-medium text-gray-400'>Solutions</h6>
            <li className='py-2 text-sm'>Analytics</li>
            <li className='py-2 text-sm'>Marketing</li>
            <li className='py-2 text-sm'>Commerce</li>
            <li className='py-2 text-sm'>Insights</li>
        <h6 className='font-medium text-gray-400'>Support</h6>
            <li className='py-2 text-sm'>Pricing</li>
            <li className='py-2 text-sm'>Documentation</li>
            <li className='py-2 text-sm'>Guides</li>
            <li className='py-2 text-sm'>API Status</li>
        <h6 className='font-medium text-gray-400'>Company</h6>
            <li className='py-2 text-sm'>About</li>
            <li className='py-2 text-sm'>Blog</li>
            <li className='py-2 text-sm'>Jobs</li>
            <li className='py-2 text-sm'>Press</li>
            <li className='py-2 text-sm'>Careers</li>
        <h6 className='font-medium text-gray-400'>Legal</h6>
            <li className='py-2 text-sm'>Claim</li>
            <li className='py-2 text-sm'>Policy</li>
            <li className='py-2 text-sm'>Terms</li>

export default Footer;

UI would be like this:


Here’s a breakdown of how Tailwind CSS is used:

  • The max-w-[1240px] mx-auto py-16 px-4 class sets a maximum width, horizontal centering, padding, and a light gray text color (text-gray-300).
  • The grid lg:grid-cols-3 gap-8 class creates a responsive grid layout: a single column on smaller screens and transitioning to three columns on larger ones, with spacing (gap-8).
  • The logo (w-full text-3xl font-bold text-[#00df9a]) utilizes full width, large font size, bold weight, and a green color.
  • Social media icons (flex justify-between md:w-[75%] my-6), from the react-icons/fa library, are displayed horizontally with spacing, adjusting width on medium screens (md:w-[75%]).
  • Sections like Solutions (font-medium text-gray-400) utilize clear headings with a slightly darker gray.
  • List items (py-2 text-sm) receive consistent padding and small font size.

You can check code result in http://localhost:3000. Best way to learn React UI is practicing on this example code, maybe tweak a bit to understand how things work.
